METHOD o|= DIGGING HOLES.-

Be it known that I, IRA DAvrD .KEMMERER, a citizen of the United Statesof America, and a resident of Nora, county of N uckolls, State of Nebraska, have yinvented a certain new and useful Method ofl Digging Holes, of which the following is a full and clear specification, reference being had to the accompaf which Figure 1 is a perspective View of the tool I employ, showing it in position to be thrust into the earth; Fig. 2, a vertical longitudinal section showing the tool thrust into the earth and the core partly formed; Fig. 3, a similar view showing the tool after it has been rotated at least once to complete the formation -of the core Fig. 4, a detailed transverse section ofthe tool, and Fig. y5 a vertical section showing the tool removed with the core adhering to it.-

The object of my invention is to provide a simple and inexpensive method of forming holes in the ground for the reception of posts, pipes, &c. f 'l Referring to the drawings annexed, a designates the shank of the too-l, b a cross-bar attached lto theV upper end thereof, and c the blade formed on the lower end of the shank. This blade is approximately crescent-shaped in cross-section, its longitudinal edges d being n sharpened `and lying parallel with each other j as to points e near the where said sharpened point f. It will thus cutting edges extend blade along each edge to the upper termination of the-blade.

The outer face of the blade is uniformly convex to a point near .thev lower end of the blade,`at which point lthe convex surface rounds nicely into the point f.

owerend of the blade, edges are tapered to a 4In carrying out my method with the above#l described tool I first scoop out a depression,

preferably having the shape of an inverted and cone, in t e earth where the hole is to be dug pour aquantity of .water therein. Then the tool is forced downward into the soil at the edge of this water-filled hole, as'shown in Figs. 1 and 2. In forcing the tool into the earth it is vibrated by means of its cross-bar handle to facilitate its entrance.

i tool has been` forced into the earth to 'the desired depth, it is rotated one or more times,

(preferably one and a half times after which operationy the core is formed and may be withdrawn by means of the tool. l Durin the act of forcing the tool into the earth the water follows the edge of the tool and causes ythe tool to give to the wall of the hole .and the Y core even sleek surfaces. It is essential that suiiicient water beemployed to make the surface of the core sticky enough to adhere to the concave surface of the tool with sufiicient tenacity to permit the core to be removed with the -tool in a single piece, .as shown in Fi .5

It will be-observed that by myfmethod the holes may be formed with great expedition,

the, process requiring for the ordinary post hole but a single operation of a few moments duration. In forming the hole Iv have found it advantageous to have theconcave'or channel part of the tool 'face the operator while the tool is being thrust into the earth. Then when it has been forced to the desired depth the operator rotates it one 7s and a half times or more thereby bringing the convex surface of the tool next to the operator.

What I claim, and desire to secure by Letters Patent, is-

The method herein described of forming holes in the earth consisting in first scooping out al portion of the earth at the point where the hole is Ato be ymade and pouring water in the said cavity, then separating the earth to e removed by a concave tool and simultaneously forming the separated body of. earth into a core the water in the cavity being caused to run or seep down into the cut formed inthe earth around the core, this water facilitating the formation of the core into IRA DAVID KEMMERER.: Witnesses: n WM.
